Hi ! My current ISPConfig server runs on DMZ with IP 192.168.1.xx, and all services are DNAT-ed from external IP (ISP #1). Now I'm going to add 2nd ISP link with 2nd external IP. Both external IPs are listed in DNS records for web / mail / ftp. Do I need to add 2nd IP in System -> Server IP Addresses, or DNS records are enough ? Thanks.
